HENRY IVELLINGTON, OF GREEN POINT, NEW YORK, ASSIGNOR TO THE AUTOMATIC GAS LAMP AND LIGHTING OOMPANY OF THE CITY OF NEW YORK.

GASOLINE STREET-LAMP.

SPECIFICATION forming part of Letters Patent No. 234,827, dated November 23, 1880. Application filed February 4, 1880.

To all whom it may concern Be it known that I, HENRY WELLINGTON, of Green Point, county of Kings, and State of New York, have invented certain new and useful Improvements in Gasoline Street-Lamps, of which the following is afull, clear, and exact description, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, the same not having been to my knowledge heretofore patented in any foreign country.

My invention relates chiefly to that class of street or outdoor lamps in which the lighter forms of hydrocarbon oil are used for fuel, being first converted into gas or vapor at or near the point of combustion, which style of lamps or illuminating contrivances are generally known as gasoline-lamps, though many features of my improvement are applicable to various styles of illuminators, whether to be used indoors or outdoors, or whether burning vapor or not.

The object of m y said invention is to simplify and improve the lantern structure, rendering the parts thereof easy to assemble for use; not liable to damage from the effects of wind or weather, from overheating of parts, or from sediment or water in the oil; easy and convenient to fill, to clean, to operate, or to pack for shipment, and not liable to get out of order when being used.

To accomplish all of this the invention involves certain new and useful arrangements or combinations of parts, as well as certain novel and useful peculiarities of construction, all of which will be hereinafter first fully described, and then pointed out in the claims.

In the drawings, Figure 1 is an elevation and partial section of the completed lamp or lantern structure, showing the parts assembled for use; and Fig. 2 is a sectional plan view of the trap upon line a; x of Fig. 1, showing the manner of securing the transparent mica disks. Fig. 3 is a perspective view of the frame G and its immediate connections.

Like letters wherever they occur indicate corresponding parts in all the figures.

A is a casting forming a water or sediment trap, located in the path of the fluid as it passes to the burner B, and serving water, sediment, or impurities, and prevent them from entering the burner. The trap is supported upon an arm, a, leading up from the collar on the post, and it, in turn, supports the burner. The fuettnbe 0, leading down from the oil-fount, communicates with the interior of the trap, and the construction is such that all the oil must pass through the trap before it can reach the burner. At D is a screw-plug, serving to permit the drawing off and discharging of the contents of the trap, being located at or near the lowermost point thereof.

At E is a secondary cleaning-plug, located nearly in line with the feeding-pipe 0, the purpose of which is to enable one to pass a wire through said tube, and thus clear the pipe itself of any sediment or obstruction, and it also operates as a valve to govern the flow of oil from the reservoir. In the sides of the trap are two transparent disks, 1) b, through which the condition of the fluid may be inspected. These disks are preferably made of mica, and are secured in place upon a gasket of cork, d, or other yielding substance, by an overlying gasket of cork, e, and by an open ring-screw, f, engaging with the walls of the trap. The mica is preferred to glass on account of its adaptability to any irregularities in the material of the packing-gaskets, whereas if made of glass these disks would be liable to become broken, owing to the pressure required to hold them in an oil tight condition. Upon the trap is also located a seat, F, for the chair or button, g, used in supporting the hinged section of the bottom plate at the mouth of the globe.

As thus constructed and arranged the trap is easy to be cleaned, a view of the contents is provided to avoid unnecessary drawing off, and it is made to form a part of the framework, upon which some of the adjuncts of the structure are made to rest, afibrding a symmetrical and sightly appearance, at the same time reducing the number of parts or pieces necessary to be used, (and consequently the cost of C0l1StIL1GtlOll,) and contributing, by reason of its immediate connection with the frame,

to retain that degree of stability about the working parts which is necessary to insure the desired durability.

In the mouth of the globe is located an open frame of metal, G, through which the pipe leadin g to the burner passes, holding theframe from lateral displacement with respect to the burner. The openings in this frame are protected by a foraminated plate in two parts hinged together, one part forming the door or lid, through which the hand or the lightingtorch may be inserted and the burner reached, and the two parts are supported upon the button g. The needle-valve stem, passing through the button, forms an axis on which the latter may be turned. This stem is, for convenience, made to project through the bottom, so as to be' accessible from the exterior; but if any short stem be employed the button or chair g maybe easily pivoted orhinged upon the seatF.

The hinged lid is kept closed by the chair, and may be opened at pleasure by simply turning the chair to one side, which movement releases the hinged part while still maintainin g the remaining section in proper horizontal position. The foraminated bottom prevents violent disturbances of air within the flamechamber, which otherwise would interfere with the successful operation of the burner.

The particular form or style of burner to be used in the lantern is no essential part of the invention, since obviously any preferred form may be adopted.

The rods H H are secured to the post by means of the collar h, their bent ends passing into recesses provided for them in the collar, and being 'held therein by the centrally-disposed post. These rods pass up through the oil-fount, pipes being therein located for their reception, as shown at i. The short pipes 11 have no communication with the oil-chamber, and their use prevents any leakage of oil at the point of union between the rods and fount. The rods are provided with nuts at top and bottom of the fount, so that said fount may be adjusted up or down until in proper position, and then securely held upon the rods. The lower ends of the rods are turned outward to fit the recesses in the collar, which enables me to apply the lamp upon any ordinary form of post, which is not possible in case the post be required to be recessed, as in some previous constructions. The bent ends of the rods form a secure union between the collar h and the general lantern structure. If, then, the collar be properly secured upon the post, (which may be of wood or metal,) the whole must remain firm, and this arrangement is very simple and easy to be applied.

The fuel-pipe is screw-threaded at each end, and at the top fits the socket provided for it in the frame which forms the fount-gage connections. The vertical tube 1 enters the bottom of the fount, near one edge thereof, and the secondary tube m enters at the opposite side, both tubes communicating through the connecting branch at, which supplies the gagetube 0 upon the exterior of the fount. This gage-tube serves to indicate the height of the oil in the tank, and it is formed by a short section of glass pipe packed at each end with cork or equivalent gaskets, '6, and held in proper place by a screw at top. This gage-frame is properly secured upon the fount, preferably by use of solder, and it affords a fixed bearing, into which the feeding-tube is screwed, giving, when the tube is first cut to the proper length, a set point, at which the assemblage of the different parts is commenced, and thus insuring their proper and easy location. After the fount is placed upon the feed'tube it is leveled up or properly adjusted by use of the two nuts upon the rods. Since the bent tube is made to form one of the supports of the fount it is easy to adjust the different parts, and this can be readily done by any ordinary workman and in consequence of this facility of adjustment the different parts may be safely packed when disconnected, thereby attbrding considerable advantage in economy of space as well as expense of shipment.

The filling-orifice K is located 011 top of the fount and in close proximity to the gage, so that the operator may readily determine the instant when the filling should be suspended. It is closed by a simple hinged cap, k, attached to the short section of pipe which is secured in the fount. The fount isannular in form, and sustains the globe, which is preferably made in one piece of glass bulged or enlarged slightly just above the fount. The fount is made to form a reflector, either by painting or polishing in the usual manner, and is of sufficient vertical depth to afford room for the name of the street or other sign. The globe rests within the fount, and may be lifted out from its annular support whenever desired for cleanin g or to replace or exchange it. Its weightis sufficient to maintain it in place, and when lowered down so as to rest within the i'ount, it is in proper position for use. Suitable springs, p 11, located upon the inner wall of the fount, bear against the globe and hold it against vibration or disturbance.

The dome is located upon the upper extremity of the globe, serving to prevent entrance ot'rain and the disturbing effects of tooviolent winds, as well as forming an ornamental top for the lantern.

The domes of all finelanterns are bronzed or painted for the purpose of protecting them from the weather and to give a finished appearance but as usually constructed the paint or coating of whatever nature becomes very much damaged by the heat from the flame. To obviate this I make the vertical exterior ring, W, to fit loosely around an interior ring, w, and large enough to allow a space for the cir culation of air between the two,which prevents any overheatin The band w rests upon the globe when the latter is in place. From the inner ring rise the standards 8 s, which support IOO the cap or upper part ofthe dome. The upper part is made of two shells, with an air-circulating space between, the outer shell, S, resting upon slight brackets t t, which preserve the proper relative location of the pair, and the two parts being firmly united by the screw-bolt w and its nut. The outer shell is painted or colored, and the inner one protected from the effects of the weather by reason of the pres ence ot'the outer one. At all times there is a circulation of air between theinner and outer shells, and this is found amply sufficient to insure against damage from overheating of the outer part or cover.

The dome is held upon the upper end of the globe by springs, as at a, which enter the mouth thereof and bear against the inner curved surface. Straight springs 3/ also bear against the innersurface of the globe, and, in connection with those at 1), hold the dome firmly in place. To remove the dome it is simply sprung off from its seat, and to replace it is quite as easy.

When constructed and arranged substan tially in accordance with the foregoing description and in a workmanlike manner, the improved lamp or lantern is found to be admirably adapted for outdoor use, fulfilling all the requisite conditions of a first-class illuminator an d attaining the several purposes or objects of the invention, as previously stated.
